Abstract: | Objective To summarize the regular pattern and state of lymph node metastasis of patients with esophageal and cardiac carcinomas, so
as to analyze factors influencing lymph node metastasis.
Methods Clinical data collected from 1,526 thoracic esophageal and cardiac carcinoma patients who were admied in the Fourth Hospital
of Hebei Medical University during a period from January 1996 to December 2004, were randomly selected and an Access Database
of the patient’s information was set up. Eight clinico-pathologic factors, including the patient’s age, tumor location and
size, pathological classification, the depth of tumor invasion, vascular tumor embolus (VTE), the state of surrounding organ
encroachment and the status of tumor residues, were identified. A correlation between these factors and metastases was statistically
analyzed using SPSS13.0 so ware.
Results Lymph node metastatic sites from esophageal carcinomas included the thoracic and abdominal cavity. Lymph node metastasis from
the superior esophageal carcinomas mainly occurred in the neck and thoracic cavity. There was a two-way lymph node metastasis
in the patients with the middle esophageal carcinoma. The inferior esophageal carcinomas mainly metastasized to the paraesophageal,
paragastric cardia, and left gastric artery lymph nodes. The rate and degree of the metastasis from the inferior esophageal
carcinomas were significantly higher compared to those of the superior and the middle esophageal carcinomas (P < 0.0125). The degree of abdominal lymph node metastasis from carcinomas of the gastric cardia was significantly higher compared
with that of esophageal carcinomas. In the group with carcinoma of the gastric cardia, the rate and degree of the lymph node
metastases in the paragastric cardia and left gastric artery were significantly higher compared to the group with esophageal
carcinoma (P < 0.05). Paraesophageal lymph node metastasis from carcinomas of the gastric cardia in the thoracic cavity frequently occurred,
too, and the degree of the metastasis was similar to that of esophageal carcinoma. There was no significant difference in
the rate and degree of the paraesophageal lymph-node metastasis between the group with carcinoma of the gastric cardia compared
to those with esophageal carcinoma (P > 0.05). Multifactorial logistic regression analysis showed that the tumor size, depth of tumor encroachment, VTE, and tumor
residues could all bring about obvious impact on lymph-node metastases (P < 0.05).
Conclusion Lymph node metastasis from superior esophageal carcinomas mainly occurs in the neck and thoracic cavity. The middle esophageal
carcinomas presented a two-way lymph-node metastasis (both the upwards and the downwards), and the lymph node metastasis from
inferior esophageal carcinomas mainly occurred in the thoracic and abdominal cardia were most commonly found in the abdominal
cavity, with frequent paraesophageal lymph-node metastasis. The sufficient attention should be paid to neck lymph node clearance
in cases of esophageal carcinoma. What is of the greatest concern is the clearance of the le gastric artery lymph nodes, and
also in cases of gastric cardia carcinoma, clearance, the paraesophageal lymph nodes. With an increase in the tumor size and
depth of tumor encroachment, and occurrence of VTE and tumor residual cells, the risk of lymph node metastasis is significantly
raised (P < 0.05).
